Fxtas

We recommend to include in the FXTAS testing guidelines both CCS hyperintensity and peripheral neuropathy and to consider them as new major radiologic and minor clinical criterion, respectively, for the diagnosis of FXTAS. FXTAS should also be considered in women or when tremor, MCP hyperintensities, or family history of FXS are lacking. Our study broadens the spectrum of tremor, peripheral neuropathy, and MRI abnormalities in FXTAS, hence revealing the need for revised criteria.
